All, I have found the problem with my low modulation in the Viking Desk. One
of the 6B4G's
in the 10 watt modulator has practically no emission and one of the coupling
caps (black beauty) between the phase splitter and 6B4G is very leaky. I
have another 6B4G on the way and tonight will change out the 4 remaining
black beauties. I suppose with two functioning tubes in the modulator driver
I will have no problem making 100 % modulation.
